INCANDESCENT GAS-LAMP.

Specification of Letters Patent.

Patented Oct. 2, 1906.

Application filed April 2, 1902. Serial No. 101.025.

To all whom it may concern:

Be it known that I, LEE T. ALTON, a citizen of the United States, and aresident of the borough of Brooklyn, county of Kings, and State of NewYork, (whose post-ofiice address is 1244 Fulton street, in said city,)have invented certain new and useful Improvements in IncandescentGas-Lamps, of which the following is a specification.

The object of my invention is to provide a new and improved incandescentgas-lamp having many new features.

It provides a lamp having a new form of the ventilator-top and animproved form of fines connecting the lamp proper with theventilating-top.

It further provides a means for regulating the flow of the gas in thedifferent parts of the lamp and for adjusting the rate of flow of gas inthe different connections of the lamp.

A further improvement exists in the means for suspending the lamp so asto avoid jarring.

Further features and advantages will appear in the followingdescription, in which reference is made to the accompanying drawings,wherein the same reference-letters refer to similar parts of myinvention.

Figure 1 illustrates a perspective view of my lamp. Fig. 1 is anenlarged side elevation of a form of connection for the supporting-bars,partly in section. Fig. 2 illustrates the suspending means connected tothe lamp. Fig. 3 illustrates the ventilating top and flues of the lamp.Fig. 4 illustrates a sectional view of the burner and the gascock. Fig.5 illustrates a perspective view of the suspending means for the lamp.Fig. 6 illustrates a vertical sectional view of the suspending means,and Fig. 6 illustrates a horizontal sectional view taken on the line 6 6of Fig. 6. Fig. 7 illustrates a vertical sectional view of the gas-cock.Fig. 8 illustrates a perspective view of the gas-cock. Fig. 9illustrates a horizontal view of the gas-cock, taken on the line 9 9,Fig. 8. Fig. -10 illustrates a sectional view of the gas-cock on theline 10 10. Fig. 11 illustrates a sectional view of the gascock, takenon the line 11 11 of Fig. 9. Fig. 12 illustrates a perspective view ofthe gas cock, showing the gas connections of the parts of the cock. Fig.13 illustrates a check which is placed above the cock and controls theflow of the gas into the mixer-tube. Fig.

a sectional view taken on the line 17 17 of i Fig. 16. Fig. 18illustrates a top view of the modified form of the check. Fig. 19illustrates a side view of the check. Fig. 20 illustrates a top view ofthe check-damper in a position different from that shown in Fig. 16.Fig. 2-1 is a section, and Fig. 22 a plan, of the double-meshburner-tip.

In Fig. 1, A indicates a supporting means for the lower part of my lamp,including the burner, globes, and flues, of which a a a of are pipesmade in two parts extending from the gas-connector a at the top of thelamp to the gas-cock casing E at the bottom of the lamp. .One of theseparts is connected directly with the main gas-supply, while the 7 otheris not connected, it being plugged at the connector (1 The two parts aa, telescope one into the other and are connected by threaded unions a aHowever, I prefer to make the connection of these parts adjustable, sothat the height of the lamp may be regulated, in which case I employ atight and telescopic joint, as illustrated in Fig. 1*. In this figure ais the upper part or gas-tube and a the lower part. 07 is a packing-cupscrewed into the end of the pipe a, and a is a gland working in the cup,and through the cup and gland and through packing (asbestos or othersuitable material) a in the cup ex tends the upper end of the pipe a.Both parts a a and a a are hollow, and each may be provided with thesliding oint. By tightening the packing the sections may be heldtogether and the gas-light and the lamp adjusted as to height. The endof the pipe 0/ l or a has a stop a, thereon to ration of the parts.

The chimney or flues B conduct the hot air from the Bunsen flame'andalsofrom the out side globe of the lamp. In order to accomplish this,and also to protect the lamp from rain or Wind, I have provided a newventilating-top which is supported on the flues. The whole is supportedby a rod 1), which is screwed into the gas-connector a. This rod 6 isprovided with pins 5. and N, which supports the fines b and b by meansof the bails 1 2'. The flue b is provided with a flange or skirt b,which supports the outside windprevent sep ashell 6 and detachablysupport the to rain-' and arms 3.

i the bracket b 3 as to allow an annular opening between the shells band the skirts b. The rain-protector b is also so su ported relative tothe flues b and the tube 5 as to give an annular opening 6 leading tothe outside atmosphere. The inner flue b is also pro vided with thebrackets 2 for supporting the top b, so as to allow an opening I) at thetop of the flue 6 By this arrangement there is a free ventilation fromthe globes of the lamp to the outside atmosphere, and yet the globes arecompletely protected from drafts of any kind and from the rain or snow.

The flues are made, preferably, in two parts which telescope one intothe other, although non-telescopic fiues may be used. As illustrated,the lower parts of the flues b 11 telescope into the corresponding partsb and b at the top of the flue. The lower part of the flue b is providedwith a skirt b for fitting over the upper edge of the outer globe (1,while the lower part of the flue b is formed into a skirt b, adapted tofit over the upper edge of the inner globe (1. Another ventilating-skirt5 is also provided for securing the outside globe d with an annularflange 4, which rests upon the upper edge of the outer globe d, theskirts b I) being united by tongues 5. The skirt Z2 is located on upperedge of the outside globe d and has a number of. openings 5 and anannular opening I) for providing a connection from the interior of theglobe d to the ventilating-flue b which permits hot air and gases toescape from the globe d and to force the superheated air encircling thechimney or flue to escape at the top, and thus help to increase thevelocity of the draft. Both the skirts I) 19 have holes 6 and 7 for thepassage of the tube a a. As the force of the draft varies with thelength of the fines, it is evident that the draft may be regulated bysliding the lamp up or down.

The burner O has a clip 0, on the top of which is located a double gauzec, fastened to the tube 0 by the annular ring or tip 0. The double gauzeis composed of two layers 8 9 of gauze so situated relative to eachother that the lower gauze 8 fits across meshes of the upper gauze 9.The size of the weave of the two parts of the gauze may vary. The weavein the two parts may be of the same size, or upper part may be of afiner weave than the lower part. These two parts can also be situated soas to permit a small airspace between them. By this arrangement of thegauzes a more perfect mixture of the gas and air is accomplished beforethe gases reach the flame, and the gauze is then protected from meltingby the intervening space between them, the lower gauze drawing ofl theheat from the intensified upper gauze. This burner-tube is supported bythe globesupporter K, which is fastened to the mixertube 0 by a.threaded screw 0 The mixertube is provided at its center with amixingchamber 10, provided with a plurality of channels 0 c and a ridge0', extending toward the interior of the chamber, so that when the gascoming from the gas-cock and the air from the damper located in thelower part of the lamp reaches the gas-mixer the gases are caused toflow in and out the chan nels and more perfectly mix, where they againexpand and further unify before reaching the burner-tube 0 The lowerpart of the mixer-tube c is provided with a hemispherical-shaped skirt0, resting upon a hemispherical piece 1 1, having openings 0 On theoutside of this hemispherical piece 11 there is located a hemisphericaldamper c having openings 0", adapted to register with the openings 0 Bymeans of the damper c the openings 0 and 0 may be caused to registermore or less, according as the amount of air for the Bunsen burner is tobe diminished or decreased, parts 0 11 forming the initial chamber ofthe tube 0 Upon the holder K the mantle of the lamp is supported bymeans of the rod A, which is fastened by means of "screws 1?, passinginto a block 12, secured to the flange 13 of the holder 7c.

The holder K comprises the annular part 14; through which the screw 0passes to fix it to the tube 0 (although the holder may be made fast tothe tube 0 and the adjustment omitted) to allow the holder to beadjusted up and down on the tube 0 to free the holder and globe cl fromthe lamp, This end, however, is secured through the telescoping of thedraft-tube. From the annular part 14 extends a flange 15, surrounded bythe annular web 16, between which and the flange 1.5 rests theburner-tube c. From the web 16 extends the flange 13. From the outeredge rises a'n apertured flange 17, through which the screw k passes,and from the flange extends the flange 18 and from this the flexible rim19. Upon the flange 18 rests an insulating washer or gasket 20, uponwhich rests the inner globe d, shoulder 21', the skirt 0, having a lug28, into which the lower end of the tube I passes and an enlarged bore29, into which the upper end of the tube "L separably and snugly passes.A damper 24, with openings 25, adapted to register with open ings 27 onthe flange 17, is placed on said flange, so that the amount of airpassing through said flange may be regulated or cut off, thus preventingall admission of air to the outside of the mantel.

Supported. on the skirt 0, located in the lower part of the lamp, is apilot-light tube 1. This pilot-tube 1 extends upward to the conter oithe burner C and through the flange 15 and at the top is provided with atip i, hav-- ing openings below the double gauze c of the burner and apassage t for the purpose of making a Bunsen flame. The tip i has a lug22 and shoulder 23 to support and steady the gauze.

The gas-cock is connected to the pilot connection I by means of the tube01 C. By means of this pilot-light the Bunsen burner may be lighted bymerely opening the gascock, as hereinafter described.

The gas-cock located in the lower part of the lamp has a number of gasconnections leading from the supply-pipe a to the pilottip i and theburner C, as illustrated in Figs. 4, 7, 8, 9, 10, 11, and 12. Thegas-plug c has a drip-opening 6 extending from a horizontal opening 6 tothe bottom of the plug. The horizontal opening e extends completelythrough the plug 6 and provides a gas connection for the pilot-jet. Atthe top of the plug is a bent passage 6 leading to the check at the topof the plug. The gas-cock casing E is provided with a plurality ofconnections adapted to register with the plug connect-ions when the cockis at diflerent positions relative to its casing. The connection 6 isadapted to register with e and eX- tends completely through the casingof the cock. There is also provided a connection (2 which extends to thecenter chamber of the casing and is adapted to register with the opening6 An opening 6 is also provided which leads from the interior of one ofthe screw-threaded connecting-arms of the cock to the pilot-lightconnection 6 also located in the gas-cock casing. At the bottom of thepilot-light connection of the gas-cock casing is provided a similaropening 6 which opens into the center chamber of the gas-cock cas ingand is adapted to register with the opening a of the plug when the plugis in such a position that it partly registers with the main supplyconnection 6. The connections 6 provides a means for turning on agreater flow of gas to the pilot-light and allowing it to flash just asthe main opening 6 leading from the gas-supply pipe a,-is opened andigniting the gas at the top of the main burner tube C.

The gas-cock casing is also provided with arms 6 e 'for connecting withthe supports (L and a. The latter support a also constitutes a means forsupplying gas to the gas cock. The gas-cock casing is also provided withan arm 6 having a tube L for preventing the turning of the cock 6 unlessa key adapted to fit the plug-stem is used. The cock-handle is soconstructed as to have a peculiar form to permit of the use of a certainkind of a key. The handle may be either square or it may be cylindrical,but flattened on one side or both sides, so that it may be turned by aninstrument inserted in the tube L. A segment of the arm 6 is removed,and

a threaded screw 6 is inserted in the gas cock, so as to control theamount 01 turning of the plug, this threaded screw a striking againstthe ends of the remaining part of the arm 6 at the limits of the motionof the cock. At the lower end the plug is provided with a drip-holder eto collect any oil that may be used to lubricate the cook or anyprolducts that may collect from the gas in the coc i.

For controlling the openings leading to the jet t" of the pilot-lightthere are provided pin valves 0 and e", which are located in thecock-casing and adapted to register with the openings 6 and e andregulate the flow of the gas through the said openings.

The operation of the cock is as follows: When the main burner C isturned off, the plug is in the position shown in Fig. 7. The gasconnection is then from the gas-supply a through the openings 6 of thegas-cock casing, the opening e of the gas cock, and the opening 6 or.the gas-cock which is controlled by the pin-valve e, which leads to thepilot-light connection t and a tube I to the pilot-jet '01. By thismeans the pilot-light is continually fed from the gas-supply during thetime that the main burner is cut off, and a small flame exists at suchtimes at the top of the burner-tube. It now it is desired to light thelamp, the plug is turned, first connecting the opening 6 with theopening 6 which al lows a greater flow of gas to the pilot-lightconnections "L than is permitted by the pinvalve 6 This causes thepilot-light to flash up just as the gas connections 6 begins to registerwith the connections e with the gascock, and the main jet at the top ofthe burnertube C is ignited. The cock is operated still further to fullyopen the connections between ICO the supply a and the burner-tubes C. At

the same time the bypass e for the flashing of the parallel jet i is cutoff from connection from the supply a, and the connection between theopening e and the gas-supply a through the arm in the casing e is cutoff. This completely cuts off any gas connection to the pilot-light andprevents any possible carbonizing of the mantle. When the main jet is tobe turned ofl, the reverse steps in the operation occurs, viz: a largesupply of gas is permitted to flow through the pilot-jet i, whichignites the pilot-jet, and upon further turning of the gas-cock apermanent connection is provided for the pilot-jet, while at the sametime the main burner is closed from the gas-supply and the main jet isturned out. The pilot-light continues to burn until the main jet isagain to be turned on.

At the top' of the gas-cock is located a check 0. Between the check 0and the gas cock casing are located a number of nuts and washers 30 31for securing the cock in the casing and the check to the top of thecock.

These also revolubly support the parts 11' and c".

The check is illustrated in Figs. 4, 13, 14, and 15, and consists of ablock having a screw-threaded opening 0 in its space, whereby it may beattached to the top 32 of the cock. In the top of the check is located acylindrical opening 33, in which may be inserted the adjustable cylinder0 The cylinder 0 has a number of rows of holes. These holes vary in sizeor in number in the rows. Above the cylindrical check is a wedgeshapedslot 0 which is adapted to register with the holes as the check 0 isturned in different positions. Attached to the check is a pin 0 forindicating the position of the holes of the check relative to the slotin the top of the check. On the outside of the check is located asegmental piece 0 over which the pointer 0 is adapted to move and toshow which row of holes is in line with the wedgeshaped slot. Amodification of the check is shown in Figs. 16, 17, 18, 19, and 20,which may be readily substituted by separating the hemispherical parts 0and 11, as well as the parts of the pilot-tube l and I. The check 0 hasa screw-threaded base similar to the check already described and isfastened to the gas-cock in the same manner. The top of the check has aplurality of holes 0 located in two separate rows on the opposite sideof the center. The damper 0 having slots 0 0, is placed on the top ofthe check 0 in such a way that the slots will register with the holeslocated on the check. The holes in the top of the check are so locatedthat the holes of one row are diametrically opposite to the holes in therow on the opposite side of the center-i. e., the position of any holein the rows is a little more than one hundred and eighty degrees or alittle less than one hundred and eighty degrees from a hole in a row onthe opposite side of the centerwhile,

on the other hand, the slots in the damper are so located relative toeach other that the ends are either diametrically opposite or are at agreater angle from each other than one hundred and eighty degrees plusthe angular distance between any two holes. By this arrangement of theslots and holes it will be seen that when the damper is secured to thetop of the check and when the damper is turned about its axis that asingle hole will appear first in one slot and then in the other,

and then again in the first slot, and so on, until the slots registerwith all of the holes of the check. There will then be first one hole inone slot and one hole in the other slot, then two holes in one slot andone hole in the other slot, then two holes in one slot and two holes inthe other slot, then three holes in one slot and two holes in the otherslot, and so on until all of the holes register with the slots. By thisarrangement I am enabled properly to distribute the inlets of the gas oneach side of the center of the check to allow a more perfect mixture ofthe gas with the incoming air, and yet to properly regulate the amountof flow without in the least congesting the pressure of the gas. Forlimiting the motion of the damper the stop 0 is located in one of theslots and fastened to the top of the check 0. By either of these formsof the check I am enabled to regulate the amount of flow of gas, and bymeans of the damper 0 located in the top hemispherical skirt surroundingthe check, I am enabled to regulate the amount of air which is fed intothe burner O, which affords a perfect regulation of the elements ofcombustion entering the main burner-tube C.

For opening the gas-cock and allowing gas to pass upward to the check Iprovide a form of a key G. This key may be of any shape; but Ipreferably use a rod having an opening in its end of such a shape as toproperly register with the handle of the cock. Upon this rod is locatedan annular nut (i which may be screwed to the protecting-tube L when thelamp is to be locked or unlocked that is, the cock is to be opened orclosed and the pilot connections is to be closed or opened and the lampis to be cleaned. A gasket g, of metal, is located on the rod and aboveannular nut cl. A second gasket 9 of rubber, is also lo cated upon thekey G and a sufficient distance below the upper end of the key G toallow room for the globe d to rest upon the gasket g and also to giveroom .to allow for cleaning out the lamp and prevent the breaking of theglobe when striking the key. The globe cl is supported by a ring 61having openings (1 to allow the air to circulate in the globe d. Thissupport (1 is fastened to the protecting-tube L by means of a nut orsplit ring 61 This split ring (Z is secured upon the tube L by means ofa bolt (1 which draws together the end of the split ring and securelyclamps it about the tube L.

When the lamp is to be cleaned, the key is to be inserted into the tubeL and, if desired, the gas-cock canbe turned off, and the annular nut dmay then be screwed into the tube L. The bolt d may be turned to unclampthe split ring 61 and the supporting-ring (P, with the globe d, may beallowed to drop on the key G until the split ring (1 and ring d reachesthe pin 9 The key G will then support the globe, since the key will beheld in the tube L by means of the gasket g. The gasket-pin is solocated as to give ample room for cleaning or fixing the lamp above theglobe (1. After the lamp has been cleaned or fixed the globe can againbe returned to its position by lifting the split ring and securing it tothe tube L, and the key G may be removed by unscrewing the annular nutd. As shown in Fig. 4, the nut d supports the key in position to supportthe globe, the washer, or gasket g when the key is dropped, resting ontop of the nut d. When used for turning the cook,

located in the head it of the buffer h the operator.

I have also provided a means for suspending my lamp so as to avoid anyjarring that may be produced by the wind or by anything foreign to thelamp, the main object being to prevent injury to the mantle. Thesuspending means H consists of a cylindrical shell h, in which islocated a buffer. The bufler may be spring-operated or it may bepneumatically operated. The connection with the gassupply may be madeeither directly through the buffer by making the bufler air-tight, or itmay be made with a by-pass for the gas, which will prevent anypossibility of leakage and yet allow free operation of the bufler. Ihave shown as a preferable form a by-pass h, consisting of a hollow andflexible metal tube h which is connected to the gas-connectors 7L2,located at the top of the suspending means and h located at the bottom,by unions 35 36 87 in the usual way. This by-pass can be made perfectlyair-tight, and thereby avoid any possibility of leakage of the gas. Thebuffer consists of a bolt 34, having a head 7b. The head h operates upona compression spring 7L5, located between the head 72. andinwardly-extending collar h, screwed to the bottom of the shell h. Inorder to prevent injury to the lamp, I have provided inwardlyextendingribs 7L7 in the shell h and notches 7L8, As the buffer moves up and downby the weight of the lamp and the operation of the spring 7?, thenotches ride over the ridges h and prevent the lamp from turning aboutits axis. It will be seen by this arrangement that the lamp will bespring-suspended, and all jarring of the mantle and of the lamp will beentirely avoided.

The structure and the embodiment of my invention may be varied in manyways without departing from the spirit of my invention. Ido not limitmyself to the particular structure shown and described, but I haveillustrated in the drawings and described merely the preferable form ofmy invention.
